Abstract
A removable core lock and key device comprises a cylinder housing ( ), a cylinder core ( ) accommodated in said cylinder housing, and an essentially cylindrical plug ( ) rotatably arranged in the core. A blocking pin ( ) is provided in the core and is movable between an extended position, wherein it engages a recess in the cylinder housing, and a retracted position. An actuator element ( ) is controlled by at least one control pin tumbler. With a control key in the lock, the control pin tumbler displaces the actuator element so that it moves the blocking pin with the rotation of said plug. With a user key in said key slot, said pin tumbler is disengaged from the actuator element and the plug is free to rotate. In other positions the control pin tumbler blocks rotation of the plug and actuator element. A simple yet reliable and secure removable core arrangement is provided.
